Dear all,

analysis tunnel adjacent to reservior for earthquake load

Submitted by hadi.habibi on Wed, 12/04/2013 - 13:59

hello dear,

i am new usre of abaqus, i try to model tunnel adjacent to reservior

my model:

- 2D model

- BCs: boundary of tunnel and reservior with rock assume be rigid (model with analytical rigid and tie to tunnel and reservior),

upstream of reservior have impedance and free surface of reservior have zero pressur.

steps: initial, dynamic implicit

- Load: earthquake acceleration apply to rigid boundary

How to get the update the local material coordinate in large deformation for hyperelasitc rubber-like materials?

anisotropic hyperelasitc

Hello,

I want to ask things about the updation of local material coordinate in large deformation.

Does there exist two ways for this?

1. Polar decomposition of Gradient Deformation Tensor F to get the rotation tensor.

2. Update each basis vector of local material coordinate system using modified Gradient Deformation Tensor F_bar = F*J^(-1/3).

What I cared about is the second method, is the second method available?

Wish someone could help me, : ). Thanks!!
